' IMPROVEMENT m I'LOUR-BOLI'S.

The Schedule referred to in these Letters Patent and making part of thesame.

Tia-whom it may concern i V Be it known that I, JOHN SKINNER, of Hadley,in theconnty of-Lapeer and Stateof-Michigan, have inventeda new anduseful Improvement in "Flour- Bolts; andJIdo declare that the followingis a true and accurate description thereof, reference being bad to theaccompanying drawing and to the letters of reference marked thereon, andbeing a part of this specification, in which- Figure 1 is a perspectiveview of myimproveinent; Figure 2 is av longitudinal vertical section ofthe same; i i

Figure '3 is a perspective view of my reel-shaft bracket; and" i Figure4 is .an elevation of the conyeyer-shaft.

hanger. I y Like letters indicate like parts in each figure. V

The nature of this invention relates to animprovenient intheconstruction of .flourrboltingdevices, and

consists in the arrangement on the one shaft of two or more reels andbolts, the one discharging its bran into 'the other, and in thep'eculiarconstruction of abrackct for supporting 'the shaft, thereby preventingit from springing; also, in the arrangement, underneath the series ofh'olts,jof a conveyer, whose shaft is inlike manner snpported inahanger,as more fully hereinafter set forth.

' In the drawing- A represents the framework of my bolting-chest,-inthe. upper part of which is journaled the reel-shaft B, which isdouble the length commonly employed, .or aboutthirty-two feet. 1 l

O 'isa reel extending fi'omthe upper end to apoint a little past thecenter, and 0, another reel of greater diameter, overlapping thelowerend of the reel 0, and

extending to the other end of the shaft B. As it is not practicable torim ashai't of more than one half the length of this without springingit, 1] support it in the middle of its length by a bracket, D,, of theform shown in fig.s3, mounted on across-beam, E, in thelower part of theframe. The jaws of this bracket embrace ajournal-beari-ng, rain themiddle of the shaft, ifit "be of metal, and in a single piece, or, if ofwood, in two sections, a gmlgeon'connecting thetwo. Each reel is coveredwith a bolting-cloth of suitable mesh.

F is the conveyer, extending, intwo sections, the full length of thebolts. It isprovided with algudgcon, 1), connecting its two sections,and journaled in a hanger, G, depending from the cross-beam E, toprevent it from springing. The conveye'r-trongh H is provided withtwo'or more discharge openings in its bottom, through which the flourmay be graded and discharged.

I do not wish to confine myself to the construction of a flour-bolttwice.the length of those now in use,

as any desired length andnumber of reels maybe employed, within areasonable diameter, for the end reels; nor to the use of but one gradeof bolting-cloth to each reel, as several numbers of cloth may covereachreel.

Motion being communicated to the reel-shaft and conveyer,.the chop isfed into the uppermost end of the smaller reel, which discl1argesthefinest flonrfirst, and so on to its end, where the coarse fiour andbran" are discharged into the next'reel, which, in like manner, permitsthe flour to pass down to the conveyer,

and discharges the bran at its lower end. The conveyer, in the meantime,conveys or propels the diiferent grades of flour along the trough untilthey reach .ztheirseveral'openings, througli which they arc-discharged.V i

Among other advantages possessed in this im provement is,-that but oneset of gears are necessary to operate it, dispensing with the separategearing for each bolt and the intermediates.

What I claim as my invention, and desire to secure by Letters Patent,is-

.. 1. In combination with the shaft B and t he reels 0' and O, thebracket 1), when constructed and arranged as described and shown, and asand for the purpose, set forth.

2. In combination with the' conveyer F, provided with the'gudgeonb, thehanger G, dependin r from the cross-beam E, when constructed andarranged as described and shown, and as and for the purpose set' forth.

' 3. The arrangement of the shaft 13, the reels 0 and Of, the bracket D,the cross-beainE, and theconveyer F, in connection with the frame A,when the several parts are constructed as described and shown, and asand for the purposes set forth.
